This is not the first time Milind Soman's mother has left us jaw-dropped.But what she has done this time will only give you fitness goals.Milind Soman recently put up a video of her mother planking in a sari a 20 sec plank for mother's day. While we drag ourselves to the gym every day (some of us don't even do that and ignore the concept of fitness altogether) Usha Soman is doing things that we can only dream of at the age of 78. He also put up some inspiring hashtags in his post one of which says #Nextispushups. What!!!
